It's the .224 SUPER Valkyrie?... Should I edit this, later?...

I'm well aware, I have several BA barrels. One of them that I ordered actually arrived, marked as an Aero Precision barrel -- since it was an all Aero build, that was a bonus.

Way less dwell time, with that long gas tube. It's enough on the 22s and 24s... Good job, man.

Then 24", with Rifle +2" gas, brother!

My first .308 carbine recoil system was from AP. It had a receiver extension that was 7.100" internal depth, a 3.8oz shorty buffer, and a weird spring that looked more AR15 carbine spring than anything else. Once I prmarily tracked my weird functional issues to the issues in the recoil system, I bought my first Armalite system, and I haven't looked back since. I have 4 other guns that are built on the Aero M5 sets - that is top-quality stuff, right there.

On the 5.56 guns, they shoot alot of hand-chamber 80-gr projectiles. May be even higher in weight now, with the 90-gr projos all over from .224 Valk. In the large-frames, it's probably 6.5mm projos, or even 6mm by now...

That $650 PSA will feel like it's "over-gassed," and you will end up buying an adjustable gas block for it, which kills your PSA warranty-forever, according to reports from them. It's not "over-gassed," it's under-recoiled, and they compensate for that in other areas. The gas tube is too short, and the gas port in the barrel is too small. So, you'll end up with the Armalite AR-10 Carbine Recoil System for it anyway, which is the cheapest way to do that setup. You'll also need the Armalite AR-10 Carbine gas tube for it, to fix the use of an AR15 Midlength gas tube, where they gas port location is drilled. You also need to include gunsmith fees to enlarge your gas port from around 0.070" that it ships with, to somewhere between 0.080"~0.085" - add that up onto the $650, and tell me how much that rifle will cost... I'm not trying to insult you, dissuade you, or anything else. I'm giving you reality. You are building this rifle, and you probably want it to run correctly, right? That's what is being offered. It might not meet your $800 budget needs, but it's not that far over it. So, you thought your budget was gonna be $800 - and it doesn't meet that. Are you going to be better off not making that budget by a few bucks? Or by meeting that budget, saving a few bucks, having a gun that doesn't run, then spending more money to replace the wrong parts that were used in the first place? Only you can answer that one...

I wouldn't run that one, either. Since you're on a new build, and this is a blank slate, and you're looking at something to run a collapsible stock on - you want to target a buffer weight that's around 5.4oz. My preference for simplicity is the Armalite AR-10 Carbine Recoil System, because it meets all the criteria, and they are the only manufacturer making it - so it doesn't get messed up by aftermarket companies, that just do what they want anyway. Next up is the DPMS-based recoil system, with the short buffer. For that, a real AR15 mil-spec receiver extension from a reputable manufacturer, make your own buffer or buy the KAK 5.3oz buffer, and use the Sprinco Orange spring. That combo just works. The recoil system is the heart of your rifle. It's not the place to try to shave a few bucks off the build. If your recoil system is junk, or made of unknown parts, we WILL be diagnosing this in the future. I guarantee it. Read these, when you get the time - the info is in there:

In the situation he just described above, it is the perfect example for what he just stated. Perfect.

True, and why most Sheriff's have giant balls. In a county, there is no higher law authority than the Sheriff. It's not often that you'll see it, but state and federal agencies better listen to the County Sheriff when they're in his county. He can shut that whole shenanigan right down, right when he decides to do so.

We all have a little bit of lesbian in us, you know that. It's okay to embrace it when you use that mentality, brother...

^^^ That right there is the key to the whole thing.

The Texas Rangers did, right away.

Yeah, SOOOO CLOSE, and got that ass-whoopin'... "Almost" only causes pain, brother... That's like somebody sayin' "I ALMOST kicked Mike Tyson's ass this one time..."

I love it!

I've been called many a time, from friends that were hunting... "Can you come out here and help me track this deer down?..." ...and I've done it. Never been in a situation with them where I've not found that deer, too. This crazy "intuition" that I have for that later led to some military training that I got involved in, which was the accreditation of a "tracking course." @edgecrusher is probably the only other person here that I ever told about that... What a badass curriculum that was... Whenever you guys need a downed critter tracked - I'm that guy.

^^^ What's more into it on there that most people never, ever pay attention to - is the bend in the gas tube,. Every single time you use an AR15 gas tube on your .308AR, you bend that gas tube out of proportion, and you're inducing more contact between the end of the gas tube, and the carrier key on the BCG. It's a height-over-bore thing, and most people never, ever understand it. Those are "midlength" -ISH tubes. PSA doesn't make an 18" rifle-length gas system, and the barrel info came from the poster. AR15 midlength gas tube (generic manufacturer) versus Armalite AR-10 Carbine Gas Tube (there's only one manufacturer, that get's it right every time).

Doc, you KILLED IT, but this one right here really hit me. I've been watching this fuk AZ up since 2005 - and that's just the first time I personally saw it happen... It was likely going on long before that, I just never witnessed it firsthand...

I LOVE IT!!! Do you have to be over 70 to use that stuff - because I'm ready NOW!...

Dimpling barrels is gay. Set screws are made to bite in to the material that you "set-screw" them into. Dimpling barrels is WAY over-rated. Line it up, and lock it down.

There's so much information about this on this board, it's not even funny. With you, having been here for a minute, you should execute your search skills. This topic is so over-talked, it'a a non-issue,for someone that's "been around" here for a minute. Especially with your credentials.

Just the fact that they tell you it's a "mil-dot bar reticle" with MOA adjustment - I'm out. Any scope that mixes those two - I'm out. If you're mil reticle, you have mil adjustments. Cool If you're MOA reticle, you have MOA adjustments. Cool. 3.4377 is the number to make mils into MOA - I can deal with that. (mil) = (inches) in target (height or width) x 27.778 / observed mils in the reticle (height or width) = yards to target. (moa)= (inches) in target (height or width) x 95.5 / observed moa in the reticle (height or width) = yards to target. 27.778 x 3.4377 = 95.4924306. Fucking Nerd Magic Math, right there. Now, I'll take that, to convert from mil to MOA, when I'm spotting mils, and my buddy is shooting MOA. I'm not going through that garbage inside my scope, with mil this and MOA that, inside the same scope, just to get a shot. It's either mil/mil, or it's MOA/MOA in the scope itself. You couldn't pay me enough to run a scope that's got a reticle in one of them, and adjustments in the other. That's a junk scope, right there, IMHO. I'm not so humble about that opinion, either.

I can talk you through this whole thing, brother. Seriously. There are some techniques that you can use that make shooting off-hand, one-handed, really easy. In a drunken stupor, I let all my cards out on the table at about 2am during the last Fall Shoot, and I gave up all my secrets to @Matt.Cross. The shiit works. We were banging steel in the dark, and making hits that I normally can't do during the daylight...
